Fuel economy

What can your tune do for a 2005 Yukon 4.8 for better mileage? Any other suggestions to accompany it? Pulling just under 20mpg on the 'state according to the DIC, would like to do better...

Thank you

Chris, I have an 03 with the 4.8. What do you get around town on highway? any aftermarket wheels, etc?

MPG will depend largely on the engine, driver, modification and gas (octane and fuel). Not to mention your right foot. I would not go off of the DIC for your economy, a hand calculation is the most accurate you can do.

FYI, the tune made mine nights and day more powerful even with the small 4.8. Now, adding the 4.10's in a week or so, and may try the Comp 212/218 cam and converter. :D
